hello, I have:
Vaillant Heizung -> VR920 -> VR700 -> Amisense Thermostatventile
VR920 -> Fritzbox ->Raspberry-> Iobroker ->Vaillant.0-Adapter
Hello, is it possible to display only the room temperature from the VR700 sensor in the HA panel?
Hello,
what HA panel are you talking about ?
Here is my climate panel:
-> 17.9 is the actual temp
-> 17.5 is the target temperature.
which lovelace card are you using ? You should have a look at the lovelace card documentation if there is a way to display info as yo want
How about, Iām using component 1.4.0 in the latest version 2020.12.1 and it works fine.
How can I detect with climate.vaillant_control_zo1 that the heating is working? The icon changes color, but in an automation I need to be able to know that it is active
Iām glad itās working fine, you should take a look at hvac_action attribute, it should be heating when itās heating.
I have added a sensor with the attribute that you indicated. Thank you

Hi @tgermain,
Looking to your work, I have two doubts:
First, do you think that we can introduce Saunier Duval/Bulex boilers under the Vaillant component as we did with vSmart and Migo?
Second, is the eBus from Vaillant the same as used in Saunier Duval/Bulex boilers rebranding? Therefore, if it is true, maybe we can use all the Vaillant stuff over the other brands without modifying the APIs.
Finally, I think that MultiMATIC is the same as MIpro under Saunier Duval/Bulex brands, with an equivalent Internet Gateway (Milink). It is possible to check cross compatibility by decompiling the manufacturers APP?
Thanks for your great job!
Hello,
thanks for your input 
I found that: https://developer.vaillant-group.com/compatibility, but not sure itās talking about multimatic API. Do you have migo ? If yes, you can just have a try with your user password.
Honestly, iām quite sceptical since the multimatic API requires a serial number (which is a number printed on the VR920 itself).
I didnāt put my hands inside my boiler, so I canāt say anything about ebus configuration.
Do you have a link to the apk ? I can have a look
Hello Thomas,
Iām really new with HA (and this forum) and my main application is my vaillant heater system (ambisense, vr920) because vaillant doesnāt have any ifttt/alexa features.
Do you have a step by step tuto or the best way is to pass through the 131 posts meaning 2 years of your work?
Thanks in advance,
Ludovic
Hello,
I didnāt realise it was already 2 years 
Actually, you just have to follow instructions here: https://github.com/thomasgermain/vaillant-component to install the custom component (last stable version is 1.4.0 now). After you have copy/past vaillant folder inside custom_components (the folder should be in the same folder as your configuration.yaml), you can go to configuration -> integration and search for vaillant. Then your enter your login/password and youāre good to go

Hello Thomas,
I copied the vaillant folder, I restarted the server but I do not find vaillant in configuration > integrations :-/
In configuration > integration I have:
- āsearch integrationā : seems to look in my already installed integrations
- ā+add integrationā : find a lot of integration but not vaillant
Is it possible to create a second multimatic user? When using the serial number of the vr920 to create a second account, it says that this serial number is already registered 
By the way Iām using
Home Assistant 2021.1.1
Frontend version: 20201229.1 - latest
Hacs 1.9.0 frontend 20201205162459
Hello Ludovic, you could try to āreload the ressourcesā and search again for vaillant integration.
What do you mean by creating a new user ? If you want to create a new user you have to do it through the multimatic app (android/ios).
Hello,
It work!
It appeared today 
I had troubles to add a user in the multimatic app. Done
Last question: is it possible to force a special mode like in the app: away, stop, heat the water,ā¦?
Thanks
yes sure, you can check:
- services: https://github.com/thomasgermain/vaillant-component#provided-services (you also have the built in climate and water_heater services)
- the expected behavior for climate and water_heater: https://github.com/thomasgermain/vaillant-component#expected-behavior

Hello,
Iām quite new on editing the dashboard but Iām still trying.
I created a button based on what I think is the variable for the water heater boost.
In the multimatic there is a mode that force the boiler for one hour.
I get an error message from ha.
I do not see a lot of available vaillant entries in the buttons options. Maybe I use the wrong button object or the wrong variable.
Also in the history log I do not see anything about the boiler
Have a nice day,
Ludo
It sounds like a bug in HA (or at least lack of consistency between doc and implementation), according to the doc, there is only 3 services available for water heater: https://www.home-assistant.io/integrations/water_heater/. So water heater is not supposed to handle turn_on and turn_off. You could use water_heater.set_away_mode instead.
In order to set a quick mode, you can use provided vaillant service: https://github.com/thomasgermain/vaillant-component#provided-services, vaillant.set_quick_mode
